Try this file:
use strict;
use warnings;
(22, 1);
Compile with "perl file".
You will even see emacs thinks the error is to be found on "line 22".

Pick your poison:

perl -wE '{my %a; $a{b}=(a=>1,b=>2,c=>3);say %a};'
perl -wE '{my %a; $a{b}=(1, 2, 3);say %a;}'

Unless you can provide an example to allow us to reproduce the error,
it's unlikely that any progress will be made on this bug report.

Do you have a perl file that allows us to reproduce this bug?

Using M-x compile in perl mode, this line can be found just fine,

Missing argument in printf at ./p line 44.

But this throws M-x compile way off track,

Useless use of a constant (6) in void context at ./p line 44.
